epl'asemen declare t rsd to 51d ment of the collars may be afforded to adapt the funnel or trough to bearings of different lengths, while maintaining the proper relation between the end and side walls of the funnel.

Having positioned the parts as indicated the molten metal, either babbitt or its equivalent, designed for use as the bushing mate rial, may be poured until an excess thereof occupies the funnel or trough above the plane of the surface of the half bearing which is being treated, to afford a surplus to allow for the shrinkage of the metal as it cools, and after the temperature has been sufficiently reduced, the side walls of the trough or funnel may be removed as indicated in Figure 5 and the surplus or projecting portions of the bushing material removed as by the operation of a punch and hammer as indicated in Figure 5.

The babbitting bar being of under size as compared with the main or drive shaft for which the bearings are designed, the surplus material at the inner surface of the rough bushing thus formed should then be removed by boring, for which purpose the boring bar 14 should be substituted for the babbitting bar, without alteration in the position of the jig or frame, said boring bar carrying double headed or double ended cutters 22 of a length accurately corresponding with the diameter of the shaft to be fit ted in the bearings and held in place for example by a key 23. The heads of the cutter are preferably of a double faced type havin a forward cutting or shearing edge 24 which is ground with the proper lead or clearance with reference to the faces 25 and 26 to out easily and shear off the bulk of the metal as indicated in Figure 7 at 27 while the cutting edge 28 is preferably finished to a size to remove only about eight orten one-thousandths of an inch as indicated in Figure 7 at .29. No lead or clearance is necessary with reference to the cutting edge 30, the same being ground to the radius or diameter of the finished bearing so as to out true to the exact size of the proposed bearing. These cutting edges when necessary may be ground across the front faces 31 and on the leading faces 25 and 26 without in any way altering their length or the size of the cut and hence the gage of the bearing which is the ultimate product of the boring operation. It will be noted moreover that the dressing or finishing of the bearing surface both as to the operation of the forward cutting or shearing edge 24: and the finishing edge 28 is accomplished by the definite boring out of the metal as with a boring cutter, in contradistinction to scraping or removing the material by a radial cut, as means of avoiding side strain and chattering.

What is claimed is:

1. A bearing replacement apparatus having a ig or frame provided with bearings or seats and a bar supported in said bearings or seats, the frame having an aligning means for engagement with an arbor disposed in the cam shaft bearing holes of a motor bed or block.

2. A bearin replacement apparatus having a jig or rame provided with bearings or seats and a bar supported in said bearings or seats, the frame having aligning means consisting of a pair of spaced lugs for straddling engagement with an arbor disposed in the cam shaft bearing holes of a motor bed or block.

3. A bearing replacement apparatus having a jig or frame provided with bearings or seats, and a bar supported in said bearings or seats, the frame having aligning means for transverse seating engagement with an arbor disposed in the cam shaft bearing holes of a motor bed or block.

4. A bearingreplacement apparatus for motors, having a jig or frame for substantially coextensive seating engagement with the under surface of a motor bed or block and carrying a bar in axial relation with the several main bearing members thereof.

5. A bearing replacement apparatus for motors having a jig or frame for substantially coextensive seating engagement with the under surface of a motor bed or block and carrying bearings in registration with the main bearing members of the bed or block, and a bar supported in said bearings.

6. A main bearing replacement apparatus for motors having a jig or frame and a babbitting bar for axial position in a hearing and carrying a pouring trough consisting of end walls and removable side walls.

7. A main bearing replacement ap aratus for motors having a jig or frame an a babbitting bar positioned in a bearing and carrying a pouring trough or funnel consisting of end walls and removable upwardly divergent side walls.

8. A main bearing replacement apparatus for motors having a jig or frame and a babbitting bar positioned in a bearing and carrying a pouring trough or funnel consisting of end walls and removable upwardly divergent side walls terminally supported by the end walls.

9. A main bearing replacement apparatus for motors having a jig or frame provided with a babbitting bar positioned in a bearing and carrying a pouring trough or funnel consisting of end walls and removable upwardly divergent side Walls terminally supported by the end walls, the end Walls being adjustable longitudinally of the bar and having a telescoping relation with the side walls.

10. A bearing replacement apparatus having a jig or frame and a babbitting bar carried thereby and provided with spaced trans- Verse collars and interposed longitudinal plates forn'iing a pouring trough or funnel.

11. A hearing replacement apparatus having a jig or fral'ne and a loahhitting; bar earried thereby and titted with adjustable eoh lars and intermediate longitudinal plates forn'iing a pouring funnel or trough.

12. A hearing replacement apparatus hav ing a jig or frame and a hahhitting bar earried thereby and titted with collars having kerfs and intermediate longitudinal plates having their end edges fitting in the kerts.

13. A hearing replacement apparatus hav ing a jig or frame and a hahbitting bar carried thereby and provided with a pouring; trough consisting of tangentially slotted collars and side plates terminally fitted in the slOtS ot' the collars.
